Re: Using Exim
c) I want that standalone server receives LAN and internet mail of LAN
When setting up exim, it'll ask you if you what range you want to act as a
smarthost for. Tell it your local network's information.
Did you mean range of IP addresses to act as a smarthost?
d) I want that users can receive their mail from mail server by their
favourite MUA in LAN.
You will also need to install some kind of POP or IMAP daemon to handle this
What is/are the "default" POP and/or IMAP server(s) of the Debian etch?
But if fetchmail receives my mail from internet and a POP/IMAP server
delivers mail in LAN, what is the purpose of the Exim then :-O?
